Surround Mode 3

DTS (DTS Digital Surround)

During playback of a DVD disc recorded in DTS format, the surround mode is set to DTS automatically.

DTS Digital Surround delivers up to 5.1 channels with lower audio compression than Dolby Digital. It provides the clarity and dynamics of the original master soundtrack.

DTS-ES (Extended Surround)

This is a new multi channel digital signal format that greatly improves the 360-degree surround impression and space expression thanks to further expanded surround signals. This format is compatible with the conventional DTS format. In addition to the 5.1 channels of DTS, DTS-ES also offers the surround back (sometimes also referred to as “surround center”) channel for surround playback with a total of 6.1 channels. For the optimum playback of DTS-ES, you need 6 speakers and a powered sub-woofer.

•The surround back channel information is matrixed into the surround left and right channels. When played with 5 speakers, the surround back channel signals are output from the surround left and right speakers so that none of the signal components are lost.

There are two formats for DTS-ES:

DTS-ES Discrete 6.1

Because the signals for 6.1 channels (including the surround back channel) are fully independent, it is possible to achieve a sense that the acoustic image are moving about freely among the background sounds surrounding the listener from 360 degrees.

DTS-ES Matrix 6.1

With this format, the additional surround back channel signals undergo matrix encoding and are input to the surround left and surround right channels beforehand. During playback, they are decoded to the surround left, surround right and surround back channels.

When DTS-ES Discrete 6.1 or Matrix 6.1 sources are decoded with a DTS-ES decoder, the format is automatically detected upon decoding and the optimum surround mode is selected.

Surround Mode 4

DTS NEO:6

With the high precision digital matrix decoder used for DTS- ES Matrix 6.1, DTS NEO:6 gives you 6.1 multi-channel surround sound from any stereo source.

• DTS NEO:6 will not work on monaural source.

DTS NEO:6 Cinema

This mode is optimized for movies.

Decoding is performed with emphasis on separation performance to achieve the same atmosphere with 2- channel sources as with 6.1-channel sources.

DTS NEO:6 Music

This mode is suitable for music.

The front left and front right signals bypass the decoder and are played directly so there is no loss of sound quality, and the effect of the surround signals from the center, surround left, surround right and surround back channels adds a natural sense of expansion to the sound field.

Dolby Digital

During playback of a DVD disc recorded in DOLBY DIGITAL format, the surround mode is set to DOLBY DIGITAL or DOLBY DIGITAL EX automatically.

Dolby Digital delivers up to 5 totally discrete, full frequency audio channels (front left and right, center, and surround left and right), plus 0.1 channel called LFE (Low-Frequency Effects). LFE delivers a separate non-directional bass signal to the sub-woofer for more dynamic deep bass sound effects.

Dolby Digital Surround EX

This mode creates the back (sometimes also referred to as “surround center”) signals from the surround left and right signals in Dolby Digital 5.1 channel source using a matrix decoder and provides 6.1 channel surround playback. With this additional channel, you can experience more dynamic and realistic moving sound.

•As the surround back channel is matrix-encoded onto the left and right surround channels, no information is lost when played with 5 speakers.

•When Dolby Digital EX sources are decoded with a Dolby Digital EX decoder, the format is automatically detected upon decoding and the Dolby Digital EX mode is selected. However, some Dolby Digital EX sources may be detected as Dolby Digital sources. In this case, the Dolby Digital EX mode should be selected manually to play these sources.
